1. The hornet nest has already been prodded, that's why we have the Decensor patchPatreon is the platform hes using so while I agree with you're statement "fuck patreon" he still shouldnt prod the Hornets nest too much.
I feel the daughters of the human, demi-human & giants will never get content as they age at a regular rate (read will never grow past childhood in the game lore vs game time if that makes sense). Goblins, demons & other monster daughter are a different matter entirely. Personally (& I can already HEAR M3ntir roll his eyes lol) I would love an Angelic Daughter to counter the Succubus. I imagine her to be a sweet sexually open, but naive, young girl with powers of love & passion (in opposition to the desire & lust powers of the Succubus). Perhaps at first they are outright enemies who see each other as "evil" who learn to love each other through their daddy.
Slough if you want hair pulling & actual fallout I reckon the best pair would be Frida & Hilde...
2. Frida and Hilda are too similar, that's just Liandra and Luthian all over again, they'll yell for a bit then hug for a bit... yawn!
3. I'm not fond of the the Angelic vs Succubi angle, it's to formulaic IMO, (and technically it's the same thing again with angels & demons being essentually the same race.)
What appealed to me about my suggestion of Victoria's Daughter vs Rosy's Daughter was neither were forced into being right or wrong, neither can be held accountable for their upbringing, they can't help that their dad is a neglectful dick who uses some of his kids as slaves while others live privileged lifestyles.
